FIELD OF THE INVENTION

The invention relates to the technical field of household appliances,specifically relating to a spraying fan.

BACKGROUND OF THE INVENTION

Along with the development of science and technology and the advancementof society, multifunctional electric products are more and more popularwith people, and the spraying fan is one of them. The traditionalelectric fan drives fan blades through the rotation of a motor togenerate air flow so as to achieving effects of ventilation and cooling,but it has disadvantages of single function of blowing and causingindoor air drying after long-time use, thereby affecting human health.Therefore, people design various spraying fans, and can use a sprayinghumidifier to humidify air while blowing air, so that on one hand, heatis taken away by water evaporation to facilitate the air cooling, and onthe other hand, moisture in the air can be supplemented in time.However, these designs suffer from the following disadvantages: 1. thehumidifying spray function and the fan cannot be used separately. 2. Thewater tank inlet is little, making it difficult to add water and cleanthe water tank, which tends to accumulate the bacterium, and furtherinfluences the health in the long-term. 3. The water tank is designed inthe product bottom which needs to be taken out when adding water and putback after adding water, which is quite complex. 4. The water is guidedinto the anatomization piece by adopting the water absorption cottonstrip to absorb water, which can become mildewed and accumulate bacteriaafter being used for a long time, which is not beneficial to humanhealth. 5. The air outlet window of the fan and fan main part adopttight and fixed structure, which can not be dismantled, leading todifficult in cleaning fan blades and dust accumulation of air outletwindow.
